TODO

General

  • Start tracking some of the samples about how they behave in various PDF viewers: Adobe Reader, Acrobat, Sumatra, Preview.app, Ghostscript, MuPDF, Evince, XPDF, Chrome's internal PDF viewer, PDF.js, Windows 10 builtin Reader,...
  • Maybe write some simple Python scripts which auto-generate the xref and the trailer given a file that already has PDF header and body of objects?
  • Other helper tools for creating hand-written PDFs: Python script which encode/decode arbitrary blobs of data (/ASCIIHexDecode, /ASCII85Decode, /LZWDecode, /DCTDecode, /FlateDecode, /RunLengthDecode, /JBIG2Decode, /CCITTFaxDecode, /JPXDecode, /Crypt). Not all at once, though...
